FAQ
Which Excel formats are supported?
.xlsx (Excel 2007+) and .xls (Excel 97–2003) are supported.
Is there a file size limit?
Up to about 100MB processes instantly; the hard ceiling is 200MB per file (limited by browser memory). For larger files, use the Split tool to break them into chunks first.
How do you ensure accuracy?
We use industry-standard diff techniques with precise row matching by key columns. For best accuracy, choose columns with unique identifiers as keys.
